Abstract

The invention relates to a device and a method for segmentally activating natural gas absorption material by using acid-alkali salt. The device consists of an absorption material reactor, an acid treatment system, an alkali treatment system, a salt treatment system and a water washing system, wherein an acid system, an alkali system and a salt system are separated from one another and respectively do circulating activation treatment on the reactor filled with absorption materials; the water is washed into the reactor so that the pH of the solution is neutral; the acid treatment system, the alkali treatment system and the salt treatment system respectively consists of liquid storage tanks and pumps and are connected with a joint of the absorption material reactor so as to form four circulating loops. The device is convenient to operate and high in activation efficiency; external warming and pressurizing are not needed; the energy consumption is obviously reduced; the device has obvious economic benefits.

Description

technical field [0001] The invention relates to an activation device of an adsorption material, in particular to a device and a method for activating a natural gas adsorption material by acid, alkali and salt in stages. Background technique [0002] For the technology of adsorbing natural gas, how to improve the adsorption performance of the adsorption material is particularly important. On the one hand, people have carefully screened, developed and utilized the adsorbent materials, and on the other hand, they have improved the process and the activation method of the adsorbent materials through continuous exploration and practice, in order to obtain high-performance adsorbent materials. [0003] At present, in the activation methods of adsorption materials, there are mainly physical activation methods (water vapor activation method, carbon dioxide activation method and air activation method, etc.) and chemical activation methods (phosphoric acid method, zinc chloride method...
